I like Diablo II too much to play Diablo III. I've played Diablo II since launch and it's probably my favorite game of all time. Diablo III isn't even made by Blizzard North, which was disbanded, and I see Diablo III as more of an appeasement throwback for people who liked Diablo, even though most people who liked the Diablo series as a whole dislike Diablo III.

However, many of the former members of Blizzard North are working for Runic Games, so I play Torchlight (which was an 11 month "prove yourselves" project, so it's very short and sweet) and am GREATLY looking forward to Torchlight II, which should be out in the next month. :D
